3 Claims. (Cl. 137-208) This invention relates to railway locomotives and more particularly to a fresh water supply system for trains and is a division of my application Serial No. 113,727 filed September 2, 1949.

It has been customary to provide coaches and berth type sleeping cars with self contained fresh water systems each consisting of a tank and connected faucet located in the aisle and/or washrooms. When the car is divided into rooms,

an individual [fresh water system is usually 10 side sills. End plate I59 is secured to the end cated in each room, but in any case the fresh posts 42 and carlines I65 are secured to the roof water systems are individual to the car. Space side plates.

Referring now to the drawings by characters of reference, numeral 4 indicates generally a railroad locomotive of the type driven by internal combustion engines. The locomotive framing includes a center sill 6, side sills 8 and rear end sill I 0. Angle members 34 are arranged above and welded to the side sills. Posts 42 are secured to the side and rear end sills and roof plates 40 are secured to the upper ends of the other air valve housing with an outlet 443 of valves 452 in such housings 438 are rotatable by handles 454 to connect the air inlet pipe 442 with pipe 444 and pipe 444 with pipes 446 and 448' for allowing air flow to the pip'es a'nd this-is the ill tanks with its ends connected thereto, a water inlet connected with the upper portion of each tank, an air pressure inlet pipe connected with the tops of the tanks, two-way valves in series in the air pressure inlet pipe located one adjacent each tank, an air exhaust pipe open to the atmosphere connected with each of said twoway valves, and an air pressure supply pipe concondition existing except when water is to be admitted to the tanks. Handles 454' are ipinned to stems 455 held in the valve casings by nuts 451 above sealing members 45 5. The valves are secured to the stems by pins 461,- The valves 452 when turned to cut offflow through pipes 444, 446, and 448, will connect supply pipes '442, 446, and 448 with vents 450 to thereby allow air to escape from the tanks and to cut off the supply of air. Gauges 456 indicate the height of water in the tanks and air pressure on "the water in the tanks is maintained at approximately 100 lbs. pressure. When the air system is open to the tanks, cock flanges 463 on one side of the valve handles 454 will overlie and lock levers 420 to maintain valves 418 closed. But, when handles 354 are moved to release air pressure from the tanks, then their position is such that valves 4! can be opened. A pressure equalizer valve 453 is connected in supply pipe 459 to hold the air at the desired maximum pressure. Pipe 459 is suitably connected with the main locomotive compressed air system which includes compressor 45!), mounted on support 462 secured to the rear portion or the locomotive flooring in advance of the tanks, driven by motor 464.

It will be noted that the tanks 405 are located at each side of the center aisle at the rear end of the locomotive leading to rear door 408. 'Thus, the tanks are out of the way and readily accessile for servicing. The rear door leads to steps 520 located above the rear coupling bar 5H5.

V The invention may be modified in various respects as will occur to those skilled in the art and the exclusive use of all modifications as come within the scope of the appended claims is contemplated.

Wh'atis claimed is:

l. In afresh water supply system for a railway train, 'apair of water storage tanks mounted in "a locomotive, water outlet pipes extending into the tanks and leading from the bottom central interior zone thereof, a train water supply line to which said outlet pipes are connected, a constantly open water level equalizer pipe extending only between and below the bottoms of said nected with one of said two-way valves, said valves each ibein'g'operable to control the flow ,of air either to- ,the tanks or from the tanks through the exhaust pipes to the atmosphere.

2. In a freshwater supply system for a railwaytrain, a pair of water storage tanks mounted in a locomotive, water outlet pipes extending through the tops of, the tanks and into the bottom central interior zone thereof, a train water supply line to which said outlet pipes are connected, a water inlet valve connected with each tank, an air pressure inlet pipe connected with the tops of said tanks, two-way valves inser'ies in the air pressure inlet pipe located one adjacent each tank, a pipe connected with each twoway valve for exhausting air from the tanks to the atmosphere, and an air pressure supply line connected with one of the two-way valves, said two-way valves each being selectively operable to control the flow of air to the tanks or to vent air therefrom through said exhaust pipes to the atmosphere and shut on the air supply 'to the tanks.

3. In a fresh water supply system for a railway train, a water storage tank carried by the locomotive of the train, a water inlet valve for the tank, means acting 'to close said water inlet valve, a water outlet pipe extending through the top and leading from the bottom central interior portion of the tank, an air pressure system connected with the top of the tank, a twoway valve in the air pressure system having a handle operable to permit flow of air through the valve'to the tank or'to exhaust .air therefrom through the valve ,to the atmosphere, and means on the handle of said two-way valve engageahle with the closure means of said water inlet valve to lock the same in closed position when said twoway valve is turned by said handle to admit air into said tank.
